3000 series aluminum coil introduction
3 series aluminum coil is an aluminum manganese alloy aluminum coil. Due to the manganese alloy element, this series aluminum plate has excellent antirust characteristics, which is also known as an antirust aluminum coil. The strength of this alloy is not high (slightly higher than industrial pure aluminum) and cannot be strengthened by heat treatment, so the cold working method is used to improve its mechanical properties.

It has high plasticity in annealing state, good plasticity in semi-cold work hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability, and poor machinability. This series of aluminum coil is often used in external packaging, mechanical parts, refrigerators, air conditioning ventilation pipes, etc In a wet environment, the product has a good anti-rust ability.

Difference between 3003 and 3004 aluminum coil
The commonly used specifications in 3 series aluminum coils are 3003 aluminum coils and 3004 aluminum coils. 3003 aluminum coil is an aluminum alloy with manganese as the main alloying element, and the manganese content is about 1.0-1.5%.
3004 aluminum coil can also be called an anti-rust aluminum coil. Commonly used outdoor, such as pipe outsourcing, aluminum veneer, aluminum composite panel, metal roof, curtain wall, and other external environments. The hardness and price of 3004 aluminum coil are higher than that of 3003, and the elongation is also higher than that of 3003.
